Dental cleanings are an important part of regular dental office visits. Performed by a dental hygienist or dentist, cleanings serve two purposes: to remove bacterial plaque and calculus (hardened deposits of plaque) from tooth surfaces missed during daily brushing and flossing; and to remove stains that can dull your smile.
There are different degrees of cleaning, including root planing that removes plaque and calculus deep below the gum line, usually for patients affected by periodontal (gum) disease. For patients in good oral health, the basic cleaning approach is known as prophylaxis, a term derived from the Greek for guarding or preventing beforehand. The techniques used in a prophylaxis remove both “coronal” (tooth surfaces visible above the gum line) plaque and staining, providing both therapeutic and cosmetic benefits.
A typical prophylaxis includes a procedure known as scaling. Hygienists use special instruments known as scalers to remove plaque and calculus by hand, or an ultrasonic device that vibrates plaque loose and is flushed away with water. The procedure removes that rough coating you often feel as you rub your tongue against your teeth, leaving the tooth surfaces feeling smooth.
Tooth polishing is a subsequent procedure to scaling that also removes plaque and surface stains. Polishing is carried out with a motorized instrument with a rubber cup in which a polishing (or “prophy”) paste is contained. The hygienist moves the rapidly rotating cup filled with the paste over the tooth surface to remove plaque and stains. The end result is a highly smooth surface and a much shinier appearance.
People with dental insurance plans are often concerned tooth polishing may be viewed strictly as a cosmetic procedure, and thus not fully qualify for benefits. This should not be the case if coded properly: tooth polishing is part of the overall prophylaxis to remove plaque and staining. The primary purpose is therapeutic and preventive; the cosmetic effect is a by-product. Most dental plans will cover one or two prophylaxes (scaling and tooth polishing) a year, but there are variations so individuals should check their plans.

Dental crowns are an essential means for restoring damaged or unattractive teeth. A well-crafted crown not only functions well, it looks and blends seamlessly with the rest of the natural teeth.
Crowns are artificial caps that cover an entire visible tooth, often used for heavily decayed or damaged teeth or as added protection after a root canal treatment. Most crowns are produced by a dental lab, but some dentists are now creating them in-office with computer-based milling equipment. On the whole, the various crowns now available function adequately as teeth—but they can vary in their appearance quality.
In the early to mid 20th Century the all-metal crown was the standard; but while durable, it could be less than eye-pleasing. Although more life-like dental porcelain existed at the time, it tended to be brittle and could easily shatter under chewing stress.
Dentists then developed a crown that combined the strength of metal with the attractiveness of porcelain: the porcelain fused to metal or PFM crown. The PFM crown had a hollow, metal substructure that was cemented over the tooth. To this metal base was fused an outer shell of porcelain that gave the crown an attractive finish.
The PFM reigned as the most widely used crown until the mid 2000s. By then improved forms of porcelain reinforced with stronger materials like Lucite had made possible an all-ceramic crown. They’re now the most common crown used today, beautifully life-like yet durable without the need for a metal base.
All-ceramics may be the most common type of crown installed today, but past favorites’ metal and PFM are still available and sometimes used. So depending on the type and location of the tooth and your own expectations, there’s a right crown for you.
However, not all crowns even among all-ceramic have the same level of aesthetic quality or cost—the more life-like, the more expensive. If you have dental insurance, your plan’s benefits might be based on a utilitarian but less attractive crown. You may have to pay more out of pocket for the crown you and your dentist believe is best for you.
Whatever you choose, though, your modern dental crown will do an admirable, functional job. And it can certainly improve your natural tooth’s appearance.
When die-hard music fans hear that their favorite performer is canceling a gig, it’s a big disappointment—especially if the excuse seems less than earth-shaking. Recently, British pop sensation Dua Lipa needed to drop two dates from her world tour with Bruno Mars. However, she had a very good reason.
“I’ve been performing with an awful pain due to my wisdom teeth,” the singer tweeted, “and as advised by my dentist and oral surgeon I have had to have them imminently removed.”
The dental problem Lipa had to deal with, impacted wisdom teeth, is not uncommon in young adults. Also called third molars, wisdom teeth are the last teeth to erupt (emerge from beneath the gums), generally making their appearance between the ages of 18-24. But their debut can cause trouble: Many times, these teeth develop in a way that makes it impossible for them to erupt without negatively affecting the healthy teeth nearby. In this situation, the teeth are called “impacted.”
A number of issues can cause impacted wisdom teeth, including a tooth in an abnormal position, a lack of sufficient space in the jaw, or an obstruction that prevents proper emergence. The most common treatment for impaction is to extract (remove) one or more of the wisdom teeth. This is a routine in-office procedure that may be performed by general dentists or dental specialists.
It’s thought that perhaps 7 out of 10 people ages 20-30 have at least one impacted wisdom tooth. Some cause pain and need to be removed right away; however, this is not always the case. If a wisdom tooth is found to be impacted and is likely to result in future problems, it may be best to have it extracted before symptoms appear. Unfortunately, even with x-rays and other diagnostic tests, it isn’t always possible to predict exactly when—or if—the tooth will actually begin causing trouble. In some situations, the best option may be to carefully monitor the tooth at regular intervals and wait for a clearer sign of whether extraction is necessary.
So if you’re around the age when wisdom teeth are beginning to appear, make sure not to skip your routine dental appointments. That way, you might avoid emergency surgery when you’ve got other plans—like maybe your own world tour!
